Two cases of Syndromes of Ophthalmoplegia , Ataxia and Areflexia were reported. A brief discussion on its clinical feature and differential diagnosis was made.
Four cases of acute viral myocarditis were diagnosed within three weeks. The clinical features, electrocardiography, cardiac enzymes and other laboratory investigations are described.
The left atrial myxoma is important not only because of its relative frequency and diagnostic difficulty but because it can be successfully removed by surgery. However, if untreated, it invariably leads to death. We report three cases seen at the Cardiology Department, General Hospital, Kuala Lumpur in 1985.
A case of acute appendicitis occurring in a 10- month-old infant is reported. The difficulties of an early preoperative diagnosis are highlighted. Perforation has usually occurred on presentation. However, prognosis may not necessarily be poor if active measures are instituted soon after perforation. The importance of active and aggressive preoperative resuscitation with fluids and electrolyte and intravenous antibiotics is stressed.
In general, psychotic symptomatology falls within the major categories of mental disorders such as schizophrenia, affective disorder and organic mental
disorder. Those that do not fit the proposed diagnostic criteria for the aforementioned disorders are usually classified under the DSM-IV diagnosis of atypical psychosis. In the eastern culture, such symptoms are accepted as part of the cultural beliefs rather than being regarded as illness. Several such cases were seen at -the University Hospital, Kuala Lumpur and two such casesare reported in this paper. Cultural influences in determining symptomatology are also discussed.
A case of the Hutchinson-Gilford progeria syndrome (HGPS) in Malaysia is described. A brief discussion of this rare condition and its differential diagnosis follows.
Cardiac amyloidosis is an uncommon and often unrecognised cause of cardiac failure. It is an infiltrative disease that may mimic either a restrictive or hypertrophic cardiomyopathy, constrictive pericarditis, coronary artery disease or valvular heart disease. The diagnosis should be suspected in a patient with cardiac failure who has low voltage complexes on the electrocardiogram, in association with increased myocardial mass and echogenicity on the echocardiogram. The definitive diagnosis, however, can only be made by endomyocardial biopsy or biopsy of any involved organ in systemic amyloidosis. Prognosis is poor and treatment ineffective.
An 84 year old man who presented with Stokes Adams syncope with exertion was found to have complete heart block on walking with reversion to sinus rhythm on recovery. The resting ECG showed evidence of ischemic heart disease with old anteroseptal and old inferior infarction but there was no recent myocardial infarction as shown by normal cardiac enzymes levels. The probable explanation for the mechanism and causation of the transient A-V block is described.
Tuberculous liver abscess is uncommonly seen in our experience. We report a case of a 17-year-old boy who presented with typical clinical features of liver abscess, where a diagnosis of tuberculous liver abscess was made on laparotomy and biopsy of the abscess wall.
Central nervous system melioidosis is an unusual infection in humans. This article reports a case of melioidosis presenting as an acute spinal epidural abscess. A discussion of this case and its management together with a brief review of melioidosis of the central nervous system is presented.
Rhinosporidiosis is a chronic granulomatous disease of the mucous membrane, predominantly of the nose and nasopharynx. It is uncommon in Malaysia but has been seen in immigrant workers from endemic areas like India and Sri Lanka. A case seen in Johor is reported here to highlight the need of awareness among clinicians at a time where there is increasing numbers of immigrant workers in our country. The causative organism of this disease is Rhinosporidium seeberi, which is found in stagnant waters. Sporangia and endospores of R. seeberi are seen in the granulomatous polypoidal lesions. The patients commonly present with epistaxis and nasal blockage. Complete excision is the treatment of choice for this disease. Recurrences are common despite anti-microbial treatment.
Cutaneous larva migrans is a parasitic skin eruption caused by migration of larvae of various nematodes. Diagnosis of cutaneous larva migrans is currently based on the clinical signs of the creeping eruption. We are investigating a new diagnostic technology called optical coherence tomography (OCT) , which is potentially able to visualize structures in the skin with an 8 microm resolution. This technology could therefore potentially allow rapid, non-invasive, in vivo diagnosis of infestations.
Coronaviruses (CoVs) are a large family of viruses that are common in many animal species, including camels, cattle, cats and bats. Animal CoVs, such as Middle East respiratory syndrome-CoV, severe acute respiratory syndrome (SARS)-CoV, and the new virus named SARS-CoV-2, rarely infect and spread among humans. On January 30, 2020, the International Health Regulations Emergency Committee of the World Health Organisation declared the outbreak of the resulting disease from this new CoV called 'COVID-19', as a 'public health emergency of international concern'. This global pandemic has affected almost the whole planet and caused the death of more than 315,131 patients as of the date of this article. In this context, publishers, journals and researchers are urged to research different domains and stop the spread of this deadly virus. The increasing interest in developing artificial intelligence (AI) applications has addressed several medical problems. However, such applications remain insufficient given the high potential threat posed by this virus to global public health. This systematic review addresses automated AI applications based on data mining and machine learning (ML) algorithms for detecting and diagnosing COVID-19. We aimed to obtain an overview of this critical virus, address the limitations of utilising data mining and ML algorithms, and provide the health sector with the benefits of this technique. We used five databases, namely, IEEE Xplore, Web of Science, PubMed, ScienceDirect and Scopus and performed three sequences of search queries between 2010 and 2020. Accurate exclusion criteria and selection strategy were applied to screen the obtained 1305 articles. Only eight articles were fully evaluated and included in this review, and this number only emphasised the insufficiency of research in this important area. After analysing all included studies, the results were distributed following the year of publication and the commonly used data mining and ML algorithms. The results found in all papers were discussed to find the gaps in all reviewed papers. Characteristics, such as motivations, challenges, limitations, recommendations, case studies, and features and classes used, were analysed in detail. This study reviewed the state-of-the-art techniques for CoV prediction algorithms based on data mining and ML assessment. The reliability and acceptability of extracted information and datasets from implemented technologies in the literature were considered. Findings showed that researchers must proceed with insights they gain, focus on identifying solutions for CoV problems, and introduce new improvements. The growing emphasis on data mining and ML techniques in medical fields can provide the right environment for change and improvement.
Vertebral fracture (VF) is the most common type of osteoporotic fracture. VFs are associated with a decline in quality of life and high morbidity and mortality. The presence of a VF is a significant risk factor for developing another fracture; however, most VFs are not clinically recognized and diagnosed. Vertebral fracture assessment by dual-energy X-ray absorptiometry is a low cost, low radiation, convenient, and reliable method to identify VFs. The finding of a previously unrecognized VF may change the assessment of fracture risk, diagnostic classification, and treatment strategies. Vertebral fracture assessment or radiographic lateral spine imaging should be repeated in patients with continued high risk for fracture (e.g., historical height loss >4 cm [>1.5 inches], self-reported but undocumented vertebral fracture, or glucocorticoid therapy equivalent to ≥5 mg of prednisone or equivalent per day for greater than or equal to 3 months).
